A new flame-brush technique is used to fabricate monomode fused couplers for application as hydrostatic pressure sensors, narrowband tunable filters and dissimilar-type fiber lateral splices. Light switching from one output port to the other in the most sensitive case was achieved with a pressure change of 8.8 psi. Wavelength tuning of a 1200 cycle-0.35 rim half period coupler was tuned over a band of 20 nm with a sensitivity of 0.013 nm/psi. Also fused couplers made of dissimilar-type fibers are proposed as lateral splices useful for efficiently exchanging power between the HEll modes of fibers with different normalized frequencies.
